Mishimoto 03-06 Nissan 350Z X-Line Performance Aluminum Radiator

Mishimoto is known for making well-built cooling components, and this X-Line Performance Aluminum Radiator is a prime example for your 2003-2006 Nissan 350Z. If you're pushing your 350Z hard on the track or in spirited driving, the stock radiator might not keep up. This upgraded unit is designed to handle more heat, keeping your engine temperatures in check when it matters most.

The engineers at Mishimoto really focused on the core of this radiator. They packed the fins in tighter, giving you a 92-percent increase in external fin area compared to the factory radiator. This means more surface for heat to escape. The core itself is also much thicker, at 36mm compared to the stock 16mm, which boosts the overall core volume by 117 percent and fluid capacity by 75 percent. The end tanks are TIG-welded aluminum, built to withstand the rigors of performance driving. It even comes with a magnetic drain plug to help catch any metal bits in your coolant, adding an extra layer of protection for your engine.

This radiator is a direct fit for your 2003-2006 350Z and includes Mishimoto's signature Lifetime Warranty, so you can be confident in its performance for years to come.
